Public bug reported: I run three Linux systems (and two windows systems) on one computer.
When running 12.04 Xubuntu, update-grub fails to produce one of the Linux menu entries because os-prober (1.51) fails to find it. When running 10.04 LTS, update-grub produces all menu entries because os-prober (1.38) finds all installed os but not a working menu entry for one because it tries to use the wrong disk for the Linux system. This is clear because it is trying to boot a Windows system and chokes on NTFS file system. The computer's BIOS will place the disk with the distribution at different places, I have seen /dev/sda, /dev/sdc, and /dev/sdg. Because of this I use UUIDs so there is no confusion. I have verified that the problematic UUID is correct, so apparently grub is ignoring this and using the "set root='(hd~,~)' " grub version 1.98-1ubuntu13 boot-info at http://paste.ubuntu.com/1101977/ ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: grub-pc 1.98-1ubuntu13 ProcVersionSignature: Ubuntu 2.6.32-41.91-generic 2.6.32.59+drm33.24 Uname: Linux 2.6.32-41-generic x86_64 NonfreeKernelModules: nvidia Architecture: amd64 Date: Fri Jul 20 09:22:41 2012 ProcEnviron: LANG=en_US.utf8 SHELL=/bin/bash SourcePackage: grub2 ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug lucid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027160 Title: update-grub produces grub.cfg that fails to boot linux To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1027160/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
